CB750 with new brake pads makes high whining noise!
« on: September 27, 2012, 02:57:05 AM »
Hi All

I have just replaced the front brake pads on my CB750 and also changed the brake fluids. The brake works fine, but it makes a very high whining noise every time I break. I have tried to brake a lot, and even tried driving with the front brake engaged to see if the noise would stop after some wear, but the noise is still there. What can I do to make the noise go away?

Couple of solutions to try....some high temp silicon grease behind the pads helps dampen down the vibration that is causing the noise. Some also cut a vertical groove in the middle of the pads. Personally I use the high temp silicone method and it works every time. Apply once a year or every 10,000 miles.

good luck
